Imagine a vicious velociraptor like those in "Jurassic Park," but only as big as a modern chicken. That's what Canadian researchers say they have found, the smallest meat-eating dinosaur yet discovered in North America. This pint-sized cousin of velociraptor, weighing in at 4-to-5 pounds, "probably hunted and ate whatever it could for its size — insects, mammals, amphibians and maybe even baby dinosaurs," according to Nicholas Longrich of the University of Calgary.

Currie report in Tuesday's edition of Proceedings of the National Academy of Sciences.

There has been plenty of evidence for large and medium-size dinosaurs in North America, but not small ones, Longrich said in a telephone interview. Now researchers see there was a dinosaur filling that niche also.

The bones of the small raptor were discovered among fossils that had been collected a quarter-century ago and remained in a museum drawer, Longrich explained.
